Workpiece Removal Detection Area Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece removal devices face inefficiencies due to frequent changes in the loading state of workpieces, requiring repeated imaging and detection over the entire area, which increases processing time and reduces operation efficiency.
Innovation Solution
A workpiece removal device and method that includes a camera for imaging, a detection section for identifying workpieces, a selection mechanism for choosing workpieces, a robot for removal, and a state determination system to assess loading state changes, allowing the detection area to be set in the peripheral region of changes, thereby reducing the scope of detection and enhancing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire workpiece loading area is imaged with a camera to detect workpieces, then detection accuracy is improved, but detection time increases
Solution Approach 1:
The workpiece loading area is divided into multiple detection regions based on loading state change information. Instead of imaging the entire area, the camera only captures images of specific regions where loading state changes have occurred, thereby reducing detection time while maintaining detection accuracy for affected workpieces
Solution Approach 2:
Different detection strategies are applied to different regions of the workpiece loading area. Regions with loading state changes receive focused detection attention, while regions without changes utilize previously stored detection data, optimizing the balance between detection accuracy and time consumption
2Speed
If the loading state determination is performed frequently to detect changes, then responsiveness to loading changes is improved, but system complexity increases
Solution Approach 1:
A feedback mechanism is implemented where the robot controller continuously monitors loading state changes and sends change information to the image processing device. This feedback loop enables rapid response to loading changes without requiring complex continuous imaging, as the system only activates detection when changes are detected through the feedback channel

AI summary
A workpiece removing device including a camera for imaging a workpiece loading area including a plurality of workpieces loaded in bulk; a workpiece detection section for detecting a workpiece, based on a camera image taken with the camera; a workpiece selection section for selecting a workpiece adapted to be removed, based on a detection result by the workpiece detection section; a robot for removing the workpiece selected by the workpiece selection section; a loading state determination section for determining whether a loading state of the workpieces in the workpiece loading area has changed due to a operation of the robot; and an area setting section for setting a workpiece detection area where the workpiece detection section detects a workpiece. If the loading state determination section determines that the loading state of the workpieces has changed, the area setting section sets the workpiece detection area in a peripheral area of a changing position of the loading state, i.e., in a portion of the workpiece loading area.
